Add group support to the simple access provider This patch adds simple_allow_groups and simple_deny_groups options to the simple access provider. It makes it possible to grant or deny access based on a user's group memberships within the domain. This patch makes one minor change to previous functionality: now all deny rules will supersede allow rules. Previously, if both simple_allow_users and simple_deny_users were set with the same value, the allow would win. https://fedorahosted.org/sssd/ticket/440
